Ingredients
Directions
Prepare
Prepare and disjoint the chicken, then roll it in the flour.
Make the soup
Melt the lard and butter in a soup kettle and fry the chicken until nearly done.
Add the chopped onion and fry together.
Pour in the boiling water and boil for three hours.
Season with cayenne pepper and coarse sea salt to taste.
Add the oysters and serve

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the meat and body of the gumbo as it simmers in the broth.
- Oysters
- Add briny flavor, and their own liquor enriches the soup as they cook.
- Flour
- Coats the chicken and helps thicken the soup as it cooks.
- Lard and butter
- Fat for frying the chicken, adding richness and browning its surface.
- Pulverized sassafras leaves
- Add the characteristic earthy, herbal aroma and help thicken the gumbo.
The step that matters
Adding the oysters. Oysters cook quickly and turn tough and rubbery if boiled too long. Adding them ten minutes before serving, just until they curl, keeps them tender.
